any one hearing Fi amps
I havent heard FI with LV but I do own the Fi Super X. 94 dB sensitivity with the LV IBX may be pushing it with the Fi 2A3 amps. However the 300b amps would be worth a consideration. Fi amps don't have a typical valve sound, i.e. they are usually not on the warm side, but rather extremely dynamic, fast and detailed. Even the 300b is supposed to have that fast detailed characteristic more than any other 300b.I think Don's amps and preamp are incredible value - they do compete at a 1/3 of the price with Shindo. For example the Fi Y didn't at all loose out to a Shindo Aurieges. A strong word of caution though: Don's amps and preamps are voiced together and because of their electrical characteristic really only work well together. Shindo preamps are a the only match I found so far and even the then Fi Y still seems at least equal.
I heard the Verdier 45 in a friends system on a pair of La Scala and while it had a lot of midrange magic, it looses a lot in the bass (even compared to other amps) and in dynamics. Hopefully I will be able to try it in my system and give you a better opinion. The 2 Watts of the 45 would certainly not be enough to drive your speakers.
The Shindo Montille should work very well. Also, I did hear the Leben and liked it a lot. The Leben would have a lot more reserve than any of the 3-8W SET amps.
